and designed. Planners and designers shall
ensure the appropriate requirements are
considered in abatement specifications for
individual projects.
c. Asbestos Training. When the Asbestos
Hazardous Emergency Response Act (AHERA)
was reauthorized as the Asbestos Hazard
Reauthorization Act (ASHARA) it mandated
specific training requirements for activities carried
out in private and public buildings as well as
schools. Specific training requirements for
inspectors, management planners, project
designers, contractors' supervisors and workers
are found in the EPA Model Accreditation Program
(MAP) in 40 CFR Part 763, Subpart E, Appendix C.
EPA agreement states may have more stringent
requirements. Ensure appropriate requirements
are included where necessary for the type of
*
asbestos related activity to be performed.
d. Building Occupancy. According to Army policy,
asbestos should be abated during periods when
area occupancy is minimal or prohibited: however,
project phasing or other critical factors may cause
buildings to be occupied during abatement. If
abatement must be scheduled while the building is
occupied, the designer must investigate the
following items before developing the contract
specifications.
(1) The ability to install critical barriers that
prevent access into and the exchange of air flow
from the abatement-regulated work area to the
occupied areas.
(2) The ability to install ventilation systems
that will continuously maintain a negative pressure
within the contained abatement work area and
provide an air change rate of at least four or more
air changes per hour within the abatement area,
thereby augmenting pressure differential between
the abatement area and the occupied area. Air
exchange rates must be calculated for the
regulated work area in order to
